SPECIFICATION forming part of Letters Patent No. 603,231, dated April26, 1898.

' Application filed June 30, 1897. Serial No. 643,973. (No model.)

To all whom it may concern:

Be it known that I, JAMES CORNELIUS, of Ridgewood, in the county ofBergen and State of New Jersey, have invented a new and ImprovedTablet-Machine, of which the follow-' ing is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedtablet-machine which is simple and durable in construction, veryeffective in operation, and arranged forready adjustment to producetablets of any desired shape and thickness and to conveniently discharge the finished product from the forcingdie of the plunger.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts .in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a like Viewof the same with parts in a different position. Fig. 3 is a frontelevation of the same. Fig. 4 is a sectional plan view of part of theimprovement on the line 4 4 of Fig. 3. Fig. 5 is a transverse section ofthe improvement, and Fig. 6 is a sectional plan view of part of theimprovement on the line 6 6 ofFig. 3.

The improved tablet-machine is provided with a base A, supporting a postor standard A, carrying a table B, open at the front and adapted tocontain the material to be formed into the tablet. j In the table B isformed an opening for the reception of the dieO, held in place inthetable by a set-screw O, engaging an annular recess in the die,'thelatter being flush with the top surface of the table," as plainlyindicated in Fig. 5. The die is provided with a central bore, which maybe ofany desired shape, it being understood that dies with .various.forms of bores may be insertedin the table B and fastened therein bythe'set-screw O to form tablets of various shapes. Into the bore of thedie 0 is adapted to pass theupper end of an anvil D, forming abottom forthe die-bore to hold the material in the bore during the time it iscompressed, as hereinafter more fully described.

- The anvilD is fitted to slide vertically in a suitable bearing Aprojecting from the standard A and containing a friction-washer D,engaging the anvil to hold the latter in position unless forced up ordown, as hereinafter described. The lower end of the anvil D is adaptedto rest on the spiral cam-sur face E, formed on top of the cam E,provided with a vertically-disposed central pin E mounted to turn insuitable bearings in the base A. The cam E is provided with an outwardly-extending arm E adapted to be taken hold of by the operator toturn the cam, so as to bring the spiral cam-surface at different pointsincontact with the under side of the anvil D to raise the latter or topermit the same to move downward, according to the dimotion in which thecam E is turned.

In the arm E is held a set-screw E, adapted to abut against a stop-pinF, removably inserted into one of a series of apertures A formed in thebase A in the segment of a circle, the center of which is in the centerof the pin E, as will be readily understood by reference to Fig. 4:.

By the arrangement described the forward swinging movement of the handleE is limited by the set-screw E striking against the stop-pin F, and itis evident that more or less turning motion can be given to the cam E byadjusting the stop-pin F correspondingly in the apertures A The handle Epreferably projects from the side of the cam at the highest edgethereof, as shown in the drawings, so that when the handle E is turnedfrom the left to the right away from the pin F until the handle E standsat right angles to the base A then the lowest portion ofthe camsurface Eis directly under the lower end of the anvil D, as illustrated in Fig.2, and the j I upper end of the said anvil is now a suitable distancebelow the lower end of the die Off When the handle E however, is in thefor ward position, with the set-screw E abutting against the pin F, theanvil D is in a raised position and extends with its upper end intothelower portion of the die 0. I

When the anvil is in an uppermost posi tion and forms the bottom for thebore of the die 0, the said remaining portion of the bore is filled withthe material for forming the tab let, and'this amount of material isregulated in quantity by the distance that the upper end of the anvilpasses into the said die 0. Now as the cam-surface E gages this upwardmovement of the die and the movement of the cam is limited by the saidset-screws E striking the stop-pin F it is evident that by adjusting thestop-pin F in a corresponding aperture and moving the handle forwarduntil the set-screw E strikes the pin the quantity of the material isgaged, and the operator is enabled to regulate the amount at will by theadjustment referred to.

A plunger G is adapted to pass into the die 0 from above to compress thematerial in the die, and this plunger G is secured by a setscrew G inthe stock II, fitted to slide vertically in a suitable bearing A formingpart of the standard A. The rear face of the stock H is formed withrack-teeth II, in mesh with a gear-wheel I, mounted to turn in a bore inthe standard A, and forming part of a handle I, secured to one outer endof the said gear-wheel. The other end of the gear-wheel is engaged by awasher I to prevent the lateral displacement of the gear-wheel in itsbearing. On the hub of the handle I is formed a cam-surface 1 adapted toengage the upper end of a rod J, fitted to slide loosely in the bearingA forming part of the standard A. A spring J presses the said rod J, soas to hold the same normally in an uppermost position. The lower end ofthe rod J is pivotally connected with an arm K of a bell-crank levermounted to turn on a pin K, secured to the bearing A previously referredto. The other arm K of the bell-crank lever extends upwardly and isprovided with a pusherarm K adapted to rest against the rear of theanvil D when the latter is in an uppermost position and to pass over thesaid anvil when the latter is in a lowermost position to push the tabletcarried onthe upper end of the said anvil off the same, so that thetablet is discharged from the machine.

The operation is as follows: Vhen the several parts are in the positionillustrated in Fig. 1, the anvil D is in an uppermost position that is,it extends into the die C--and the plunger G is likewise in an uppermostposition above the table B, so as to permit of filling the die with thematerial to be formed into the tablet. Vhen this has been done,

the operator swings the handle I over into.

the position shown in Fig. 2, whereby the gear-wheel I is turned and thestock H with: the plunger G is moved downward and the lower end of thesaid plunger passes intothe die and compresses the material thereinagainst theanvil D, which forms-the bottom for the die. operator takeshold of the handle E and swings the same to the right into the position.

shown; in Fig. 2 to bring; the lowest point of thecam-surface E underthe anvil D. As soon; as this has been done the operator presses thehandle I still farther downward into a, lowermost forward position, soas to push the formed tablet, together with the an- XVhen this has beendone, thevil D, downward until the tablet is out of the die below thetable B, as shown in Fig. 5, it being understood that the anvil D slidesdownward in its bearing A and is finally held therein by thefriction-washer when the handle I is in its lowermost forward position.

3 Vhen this has been done, the operator swings the handle I back to itsformer position and :in doing so brings the cam-face I over the upperend of the rod J, so that the spring J thereof now forces the rod Jupward, whereby a swinging motion is given to the bell-crank lever andthe pusher-arm K thereof moves forward to push the tablet oif from theupper end of the anvil D. It then immediately recedes back to its formerposition, as the camface I passes off the upper end of the rod Jprevious to the arm I reaching its final position, as shown in Fig. 1.The operator now again takes hold of the handle E and turns the cam Eback to its former position-that is, until the set-screw E strikes thestop F, so that the anvil D is raised into its uppermost position. Theabove-described operation is then repeatedthat is, the die is againfilled with the material and the arm I is swung forward to compress thematerial so as to form the tablet.

It will be seen that by the arrangement described the operator isenabled to readily adjust the anvil D in the die, according to theamount of material desired to be pressed into the tablet, and theoperator is also enabled to readily exchange the die, anvil, and plungerfor other difierent shapes whenever desired.

Having thus fully described my invention, I claim as new and desiretosecure by Letters Patent 1.
